COMPACT BIDIRECTIONAL REVERSIBLE AUTOSWITCH
6. Troubleshooting

6.1 Common Problems

1. Check all the cables. We recommend you use
IEEE 1284 cables.
2. Use the optional AC power adapter. The
Autoswitch is usually powered by the signal drawn
from the computer and parallel device parallel
port. However, if the computer or the device fails
to supply enough power to the Autoswitch, a
9-VDC, 500-mA power adapter can be used. We
recommend using the power adapter on inkjet
printers like the DeskJet®.
3. Adjust the timeout. If you print long document files
with graphics, or use a printer spooler, adjust the
timeout to a higher value. This is because as the
computer processes complex files, it pauses more
often. If the pause is longer than the timeout
window, the Autoswitch will assume that the
transmission is over and prematurely finish the job.
